Protein sensitive hairI usually love everything I try from Kerastase. However this one was a miss for me! It dried my hair out and caused a lot of flat frizzy waves. I was pretty surprised. I started doing some research and learned about protein sensitivity. In the past I had purchased some other products from a different company that had a lot of protein In them and they did the same thing to my hair. I didn’t realize at the time it was the protein, I just thought they didn’t work for my hair. So my recommendation is to buy some cheaper protein rich products and try them out before buying this to make sure your hair isn’t protein sensitive. I hate giving a bad review because I love Kerastase and I’m sure this mask works really well for most hair! Oddly enough the discipline shampoo, fluidissime spray and oleo-curl cream don’t do this to my hair and they work wonderfully. I guess they don’t have as much of the keratin in them as the mask does.

Great hair mask!I have been using Kerastase shampoo for years. This time I decided to give the mask a try. After suffering from dry damaged hair after using coconut oil which totally ruined my healthy hair, I ordered this mask. First I got red off my damaged heir by getting a good hair cut and getting red off the coconut oil ,then I started using this mask. I must say this is a great product. It does what it says it will! My hair is shiny and looks very healthy. I used once or twice a week. I love the look and feel of my hair. Absolutely worth the price!

Best hair treatment ever for curly hair!!!If you blow dry or flat iron your hair daily, this mask is a must have!! I started using the maskertine line of products 3 weeks ago and the difference was clear from the first use. I have curly thick hair that I can blow out to a smooth wavy style very easily. The shampoo and mask combo used daily is fantastic. My hair is smooth VERY shiny and my salon color is locked in! No brassy colors here:-)
Don’t worry about the price, because you only need to us a little bit. This lasts a long time and it actually works! Really holds up to the humidity too.

A Miracle.I have dense, frizzy hair and have gone through all the luxe brands, thinking they worked and being really neurotic about my product lineup. I casually tried this mask and was shocked - it blows everything I’ve ever tried out of the water. It is astoundingly good.

There is nothing like itI am in love with this mask. It totally transforms my dry, frizzy hair into silk. I barely need a leave in product after this mask, just rinse it out and let my hair air dry. Or when I go out, I blow dry, and curl my hair and this mask totally makes it look and feel healthy, shinny, beautiful. Yes expensive. But it lasts a while and I have never found anything that comes even close to this, so I have bought multiple jars over the years. My favorite. :-)

Best conditioner everThis conditioner transformed my hair! I have frizzy, wavy-curly hair, and this combined with the shampoo makes my hair look like i got it professionally keratin-treated.
